RAIL-CAR TRUCK MOUNTING Filed June l5, 1961 2 Sheets-Sheet 2 //V VE/V'OR FRA/VK KENNEDY l Affomey United States Patent() 3,057,307 RAIL-CAR TRUCK MOUNTING Frank Kennedy, Johnstown, Pa., assignor to United States Steel Corporation, a corporation of New Jersey Filed .lune 15, 1961, Ser. No. 117,205 2 Claims. (Cl. 10S- 200) This invention relates generally to railway cars, and more particularly to devices for fastening railway trucks and bodies. This invention is particularly suited for use in heavy-duty railway cars used in the steel industry for transporting ingot molds or other heavy objects.

It is a principal object of this invention to provide a fastening device which will prevent the separation of railway trucks and bodies in case of accidents.

A more particular object of this invention is to provide a device for fastening railway trucks to bodies which is easily replaced and removed, yet which will provide a positive lock against separation of the truck and bodies.

Other objects will appear and a fuller understanding of this invention may be had by reference to the following description and drawings, in which:

FIGURE l is a plan view of a railway truck fastened to a body according to this invention;

FIGURE 2 is a sectional view taken along the plane designated by line II-II of FIGURE l;

FIGURE 3 is a longitudinal sectional view taken along the plane designated by line III-lll of FIGURE l; and

FIGURE 4 is a perspective view of one end of the fastening device.

Referring now to the drawings, a heavy-duty railway truck is designated by the reference character 10. The truck includes a truck bolster 11 which has a vertical opening 12. The truck also includes a rocker pin 13 spaced below the truck bolster 11 which holds together a pair of brackets 14 mounted on side sills 15.

A body 20 is supported on the truck 10 by a body bearing 2-1 which provides for relative horizontal rotation between the truck and the body 20. This type of mounting accommodates movement of the body relative to the truck when the car passes laround a curve or over uneven track. The bearing 21 has a vertical opening l22 aligned with the opening 12 in the truck bolster. A body bolster 23 is provided and has a vertical opening 24 aligned with the openings 12 and 22. The opening 24 is counter 4bored as shown at 25 at the upper end which counter bore terminates at a shoulder 26 spaced below the ood bed `27.

The fastening device of this invention includes a king pin 30. The king pin 30 has an eye loop 31 formed at one end thereof which loop surrounds the rocker pin 13. The pin 30 has a shank 32 extending through the openings 12, 22 and 24, and terminating at an end portion 33 disposed in the counter bore 25. The end portion 33 is threaded for the reception of a cap 35.

The cap 35 is threadedly engaged on the end portion 33. The cap 35 includes a ilange 36 which is normally spaced from the shoulder 26 when the cap is threaded on the king pin. The flange 36 is positioned to abut the shoulder 26 upon relative separation movement of the body and the truck 10. The spacing of the flange 36 from the shoulder 26 provides for limited movement between the body and the truck due to weight variations on the body, but prevents separation of the body and the lCC truck. Thus, upon an accident, which would tend to separate the body from the truck, such separation will ybe prevented by the abutting of the fange 36 and the shoulder 26.

The cap is beveled at its lower end as shown at 37. This bevel will provide a clearance between the lower portion of the cap 35, and the shoulder `26, thus preventing any seating of the bottom of the cap on the shoulder 26 as a result of an accident.

Constant jarring and movement of the truck and body often tends to loosen the cap; hence, a locking device for the cap is provided. The locking device includes a plate 3S welded to the top of the cap, and which is a part thereof. The plate 38 has three circumferentially spaced apertures 39. Three threaded holes 40 are similarly spaced on the end of the -king pin and are aligned with the apertures 39 when the cap is threaded on the kingr pin. Three cap screws 41 project, one through each aperture, and are threaded into the holes 40. This secures the cap 35 firmly in place and prevents unintended loosening of the cap. Preferably, the tops of the cap screws 41 lie below the floor bed 27 of the body. For maintenance and repairs the cap screws 41 may be removed by any conventional wrench, and a special three pronged tool (not shown) is used to remove the cap 35.

While one embodiment of this invention has been shown and described, it will lbe apparent that other adaptations and modifications may be made without departing from the spirit and scope of the following claims.

I claim:

1. In a railway car having a body and a truck and a bearing rotatably supporting the body on the truck, a body bolster carried by said body and a truck bolster carried by sai-d truck, a rocker pin carried by said truck below said truck bolster, the truck bolster, the bearing, and the Ibody bolster having vertically aligned openings therethrough, the opening in said body bolster being counter bored at its upper end, said counter bore terminating at a shoulder, the combination therewith of a king pin, said king pin having an eye loop around said rocker pin, said king pin having a shaft extending through said openings and terminating at a threaded end portion disposed in said counter bore, a cap threadably engaged on said end portion of the king pin, said cap having a ange disposed in said counter bore, said frange being selectively positionable with respect to said shoulder by rotation of said cap on said king pin, said cap having an end plate, said end plate having a plurality of apertures and the end portion of said king pin having a like number of threaded holes therein, said apertures and said holes on the king pin Ibeing aligned, and a screw passing through each aperture and threadably engaged in the aligned hole to prevent rotation of said cap whereby the selected spacing of said flange is maintained, said cap having a lower end normally positioned below said shoulder, said lower end being beveled to prevent seating of the lower end of the cap on the shoulder when the body moves with respect to said king pin.

2. In a railway car having a 4body and a truck and a bearing rotatably supporting the body on the truck, a body bolster `carried by said body, a bearing on the bottom of said body and a truck bolster carried by said truck, a rocker pin carried by said truck below said truck bolster, the `truck bolster, the bearing, and the body bolster having vertically aligned openings therethrough,

the opening in said body bolster being counter bored at its upper end, said counter bore terminating at a shoulder, the combination therewith of a king pin, said king pin having an eye loop around said rocker pin, said king pin having a shaft extending through said openings and -terminating at a threaded end portion disposed in said counter bore, a cap threadably engaged on said end portion of the king pin, said cap having a flange disposed in said counter bore, said ange being selectively positionable with respect to said shoulder by rotation of said cap on said kingl pin, and at least one screw passing References Cited in the le of this patent UNITED STATES PATENTS Bayley Sept. 4, 1883 Geiger Feb. 18, '1930 OConnor Oct. 21, 1930 Cross Aug. 9, 1960
